Chemical Properties of Radon

    On the average, throughout the world, one part of radon is present to 1 x 10²¹ part of air. At room temperatures radon is a colorless/odorless gas but when radon is cooled below the freezing point, radon exhibits a brilliant luminescence which turns yellow as the temperature decreases and orange-redish at the equivalent temperature of liquid air. Radon is an inert gas therefore it is a noble gas but research has shown that radon does react with fluorine, forming a fluoride. Radon is also the heaviest known gas and although radon is usually found in rock beds it has been found in some water springs.

• Radon does not react with air
• Radon does not react with water although it does dissolve slightly to the extent of about 230 cm³ kg^-1 at 20°C (293 K)
• Radon gas doesn't react with any halogens except fluorine. Radon gas reacts with fluorine to form the difluoride radon(II) fluoride, RnF₂, but the compound cannot be characterized.
• Radon does not react with any acids or bases
